NIR joulemeter

An addition to the deltΔ series joulemeters, the deltΔ NIR joulemeter from Spectrum Detector Inc. provides NIR spectral response from 0.9 to 1.7 μm. The delt series devices are compact, flexible and economical. Users can plug a delt probe into an analog power module to work with oscilloscopes and lock-in amplifiers, or into a digital USB-based electronic module to create a personal computer-based energy meter. LabView software controls range, wavelength, trigger level and graphic displays.
